NASA global warming alarmist James Hansen, who previously endorsed a book that called for acts of environmentalist terrorism and genocide to return the planet to the agrarian age, is set to call for a global tax on carbon emissions in an upcoming speech.

“In his lecture, Hansen will argue that the challenge facing future generations from climate change is so urgent that a flat-rate global tax is needed to force immediate cuts in fossil fuel use,” reports the Guardian.

Echoing rhetoric that skeptics of the political agenda behind man-made climate change are akin to racists, Hansen characterizes alleged human-induced climate change a “great moral issue” on a par with slavery.

The report admits that the tax would “greatly increase the cost of fossil fuel energy” even as people struggle with soaring energy costs and that the “the carbon levy would increase year on year.”
